Payload is the carrying capacity of an aircraft or launch vehicle, usually measured in terms of weight.Depending on the nature of the flight or mission, the payload of a vehicle may include cargo, passengers, flight crew, munitions, scientific instruments or experiments, or other equipment.Extra fuel, when optionally carried, is also considered part of the payload.hen the weight of the payload and fuel are considered together, it is known as the  useful load fraction . In spacecraft, mass fraction is normally used, which is the ratio of payload to everything else, including the rocket structure.
And in fact, âcarrying capacityâ in reference to a school bus or an elevator is not all that different from carrying capacity in reference to a population. On a school bus, the carrying capacity would be the maximum number of people that could safely fit. In ecological terms, carrying capacity is defined as the maximum number of a species that can sustainably live in a given area. In other words, a populationâs carrying capacity is the size at which a population can no longer grow due to lack of supporting resources. All populations have a carrying capacity, whether bacteria in a bottle or rabbits in a forest.
